Headless Chrome as a Service

All the rendering power of headless Chrome without managing it yourself. We handle Chromium updates, memory, crashes, and scaling. Just send a URL and get a screenshot.

Code Examples

cURL

Python

Node.js

# Headless Chrome renders the page, you get the screenshot
curl "https://snapapi.tech/v1/screenshot?url=https://example.com&api_key=YOUR_KEY&width=1920&height=1080" \
  -o screenshot.png

# Wait for JavaScript-heavy SPA to render
curl "https://snapapi.tech/v1/screenshot?url=https://spa-app.com&api_key=YOUR_KEY&delay=3000" \
  -o spa.png

import requests

# Chrome renders the page server-side — you just get the image
response = requests.get("https://snapapi.tech/v1/screenshot", params={
    "url": "https://example.com",
    "api_key": "YOUR_KEY",
    "width": "1920",
    "height": "1080"
})
with open("screenshot.png", "wb") as f:
    f.write(response.content)

const res = await fetch(
  "https://snapapi.tech/v1/screenshot?" + new URLSearchParams({
    url: "https://example.com",
    api_key: "YOUR_KEY",
    width: "1920",
    height: "1080"
  })
);
require("fs").writeFileSync("screenshot.png", Buffer.from(await res.arrayBuffer()));

Capturing screenshot...

Why SnapAPI?

No Browser Setup

We run Chromium so you don't have to. No Puppeteer, no Selenium, no drivers.

PNG, JPEG, WebP

Choose your format. Set quality. Get optimized output.

Mobile Emulation

9 device presets — iPhone, Pixel, iPad, desktop. One parameter.

Full Page Capture

Scroll the entire page and stitch into one image. Automatic.

Element Selector

Capture a specific element by CSS selector instead of the whole page.

Dark Mode

Emulate prefers-color-scheme: dark to capture dark-themed pages.

Automation workflows — add screenshots to CI/CD, reporting, and alerts

How It Works

1. Sign up for a free API key — 100 screenshots/month, no credit card required.

2. Make a GET request to /v1/screenshot with your URL and API key.

3. Receive a pixel-perfect screenshot as a binary image, or JSON with metadata if meta=true.

That's it. No browser installation, no Chromium management, no headless infrastructure to maintain.
